Seasoft for Windows 7 Fast Track 2008
1). Turn on deck unit and be sure the display is non-zeros.
2). In Seasave v7, select RealTimeData/Start from the menu.
3). Do Not store data on disk immediately so select “Begin archiving data when the start archiving command is sent”.
4). Click [Select Output Data Filename] and label the station’s data file (YYMM###.hex)
5). Be sure the Instrument configuration file is YYMMDoNotMove.con
6). Click [Start] then fill out the header form which should include:
• Ship: (Full Name ex New Horizon)
• Cruise: (YYMMSS ex 0808NH)
• Station: (LL.L SSS.S ex 93.3 120.0)
• Cast: (### ex 017)
• Operator: (Initials ex DMW)
• Cast Type: (PRODO, ROS, SCCOOS, ANCILLARY)
7). Click [OK] on the “data not saved reminder”
8. Record deck pressure from fixed display 2 (right middle screen).
9). Deploy the CTD over the side, tell the winch to “zero at surface and take it to 10m”.
10). Start the 2 minute timer.
11). While waiting, activate the Knudsen depth recorder, find & record bottom depth. Use the “cheat sheet” to adjust the proper depth window on the Knudsen. If this takes longer than 2 minutes and the depth is known to be deeper than 550m, come back to this task after starting the CTD downcast. As it is going down, keep adjusting the Knudsen until you get a definite bottom. If the weather is rough, this may be futile so note it on the console ops.
12). After 2 minutes on the timer, return CTD to surface.
13). ***VERY IMPORTANT*** Start recording data to disk by pressing RealTimeData/Start Archiving . Verify the data is saving to disk by confirming the “archiving data to C:\YYMMSS\YYMM###.hex” just below the top toolbar menu.
14). Send the CTD down to 515m (bottom depth permitting, otherwise to within 10m of bottom) at 30m/minute. After 100m, ask the winch to speed up to 50m/min, weather-permitting. If it is rough, continue down at 30m/min to terminal depth; if REALLY calm you can go 60m/min.
Use the altimeter to adjust the terminal depth if it is shallower than 515m or a basin station. If the weather is calm (very little ship roll), you can adjust the terminal depth to ~5m off the bottom if it results in a extra bottle depth (ie 10m or more from the next closest bottle).
15). Using the chl max visible on the downcast, select the cast-type console operations log. 0-50m Chl max = type I; 50-125m chl max = Type II; chl max >120m = Type III
16). When 515m of wire out is reached, be sure the pressure is 515m or deeper. If not, pay out more wire till 515m is reached. Once the terminal depth is reached, record the wire-out, time-stopped, pressure (to tenths); temperature, conductivity, and salinity (all to 3 decimals); altimeter if shallow. After 20+seconds, click [Mark Scan] then [Fire Bottle] then, for the 1st trip only, [Add to .Nav File]. Record the Tripped time and check the confirmation boxes (mrks & fired counts have incremented by +1).
Before starting up, record the Time, Bottom Depth, Lat & Lon in the Rosette Start Up box on the Console Ops.
17). Adjusting for wire vs pressure differences, tell the winch the next desired depth from the Console Ops. Upcast winch speed can be 50+m/min.
18). When possible, verify the number of open bottles upon arrival to surface. Trip your surface bottle(s) and leave the data acquisition running while retrieving the CTD
19). Record the final deck pressure, Real-Time Data/Stop, then <Ctrl><Alt>B to backup.
20). Refer to CTD Post-Cast Tasks for more info on post-cast duties.
